Abstract Anticipating distractors during working memory maintenance is critical to reduce their disruptive effects. In this study, we aimed identify the oscillatory correlates of process across different spatial scales neural activity. We simultaneously recorded local field potentials (LFP) from LPFC and electroencephalograms (EEG) scalp monkeys performing a modified memory-guided saccade (MGS) task. The were required remember location target visual stimulus while anticipating distracting stimulus, flashed at 50% probability delay period. found significant theta-band activity anticipation distractor, closely linked with underlying dynamics, through decoding cross-temporal generalization analyses. EEG particularly reflected reactivation around anticipated time even in absence stimuli. During time, beta-band exhibited transiently enhanced intrahemispheric communication between occipitoparietal brain areas. These phenomena observed only when successfully performed task, implicating possible functional role mitigating distractors. Our results demonstrate that distractor recruits multiple processes maintenance, key predominantly theta beta bands.

Introduction Anticipating distractors during working memory maintenance is critical to reduce their disruptive effects. In this study, we aimed identify the oscillatory correlates of process across different spatial scales neural activity. Methods We simultaneously recorded local field potentials (LFP) from lateral prefrontal cortex (LPFC) and electroencephalograms (EEG) scalp monkeys performing a modified memory-guided saccade (MGS) task. The were required remember location target visual stimulus while anticipating distracting stimulus, flashed at 50% probability delay period. Results found significant theta-band activity anticipation distractor, closely linked with underlying dynamics, through decoding cross-temporal generalization analyses. EEG particularly reflected reactivation around anticipated time even in absence stimuli. During time, beta-band exhibited transiently enhanced intrahemispheric communication between LPFC occipitoparietal brain areas. These phenomena observed only when successfully performed task, implicating possible functional role mitigating distractors. Discussion Our results demonstrate that distractor recruits multiple processes maintenance, key predominantly theta beta bands.
